--- Comment #2 from Jean-Baptiste Mardelle <j...@kdenlive.org> --- Thanks for your report. After some testing, I could reproduce a crash, here is what happens: When resizing the rectangle in the monitor window, you can create very small rectangles, but not smaller than 1x1 pixel. This does not cause a crash. However the problem is that the motion tracker created keyframes using the deprecated smooth type, which could cause overflow. This means that when moving from a large rectangle to a very small one and back again to a large one, we could be in a situation there the rectangle is null, which caused the crash. I fixed this by enforcing keyframes to use the more recent smooth_natural type which doesn't have this issue. It would be great if you could test the latest development build of Kdenlive that contains my change to confirm if it fixes the issue for you.
